Tandem MIG
Flat and Horizontal Lap Welds
1.5 mm - 5 mm
Automotive, Tank Fabrication
Flat and horizontal lap welds common to automotive
components like control arms, stub or full chassis
frames, cross members, shock absorbers, struts,
stabilizer arms and flex axles are performed at welding
travel speeds ranging from 70 - 130 ipm. On thinner
components with metal thickness ranging from
1.5 - 3 mm, flat and horizontal lap welds are made with
(2) .035” diameter electrodes at travel speeds ranging
from 100 - 130 ipm. Thicker components with metal
thickness from 3 - 5 mm are performed with (2) .045”
diameter electrodes at travel speeds ranging from
70 - 100 ipm.
Flat and Horizontal Fillet Welds
3 mm - 6 mm
General Light Gauge Steel Fabrication,
Shipbuilding, Railroad
Light gauge steel fabrication of 3 - 4 mm fillet welds
used to weld structural trusses, farm implements,
residential and commercial storage systems,
trash-hauling containers and similar components are
welded with (2) .035” diameter electrodes to produce
welds at travel speeds ranging from 80 - 100 ipm.
Larger 4 - 6 mm fillet welds common to structural
beams, light earth moving equipment, ship stiffeners,
rail cars and similar components are welded with
(2) .045” electrodes at travel speeds ranging from
50 - 80 ipm.
Joggle Joints 1.5 mm - 4 mm
Tanks and General Fabrication
Joggle joints require a careful balance of joint fill and
controlled penetration. Tandem MIG provides the
independent control of both, providing needed joint fill
without excessive penetration. Joggle welds between
1.5 and 3 mm, common to the light tank, truck bodies,
trash-hauling containers and similar components are
welded at travel speeds ranging from 80 - 120 ipm
using (2) .035” diameter electrodes. Larger 3 - 4 mm
joggle joints used in larger tanks and thicker
containers are performed at welding speeds ranging
from 40 - 80 ipm using (2) .045” diameter electrodes.
High-Speed and High-Deposition Welding
This thin gauge lap weld was made at a
travel speed of 100 ipm
